In order to ensure, in a cup-shaped container, that the base can be pressed out in a trouble-free manner even with an economical use of materials and is sufficiently stable after moving from one position into another, radially extending groove- or rib-shaped profiles which converge to form a hollow central area are provided in the base. The height of the said profiles of the base advantageously decreases from the central area towards the outer ends of the profiles.
